GAS-ENGINE EXHAUST-FURNACE. l

SPECIFICATION forming part of Letters Patent No. 485,988, dated November8, 1892.

Application filed March 17, 1892. Serial No. 425,307. (No model.)

To a/ZZ whom t may con/cern;

Beit known thatI, HIPPOLYTE JOSEPH SEIG- NEURET, of Henderson, in thecounty of Sibley and State of Minnesota, have invented a new andImproved Gas-Engine Exhaust-Furnace, of which the following is aspecification, reference being had to the annexed drawings, forining apart thereof, in which Figure l is a vertical longitudinal section of myimproved gaso-steam engine. Fig. 2 is Vertical transverse section takenon line in Fig. l. Fig. 3 is a Vertical transverse section taken on liney y in Fig. l, and Fig. 4 is a horizontal section taken on line ea inFig. l.

Similar letters of reference indicate corresponding parts in all theViews.

The object of my invention is to combine a gasengine and a steam-enginein such a manner as to utilize the heat contained in the products ofcombustion in the gas-engine in the generation of steam for propellingthe steam-engine.

My invention consists in the combination, with the steam-boiler, of agas-engine placed in the water-space of the boiler and arranged toexhaust into the tire-box or combustionchamber of the boiler, all aswill be hereinafter more fully described.

The gas-engine A, which is used in connection with the boiler B, may beof any wellknown type. In the present case I have represented an OttoVertical gas-engine, the cylinder B of Which is placed in the waterspacect of the boiler. The water-space in this case is located in the end ofthe boiler corresponding with the frontend of the firehox, and betweenthe said water-space and the flue-sheet ZJ there is a combustion orheating chamber C. In the present case the gascylinder B of thegas-engine A is provided with a Water-jacket c, which communicatesfreely with the Waterspace in the boiler through apertures d, formed inthe jacket; but the outer jacket may be dispensed with and the Water maybe brought into direct contact with the walls of the cylinder. Thegasengine being of ordinary construction Will require no description.

The gas-supply pipeeis connected with the gasoline-tank (or gas-supply)D, and air is drawn in through the induction-pipe E, and the charge iscompressed in the usual way and ignited by electricity or in an y otherde sirable way. The hotl products of combustion resulting from theexplosion of the gas In the cylinder B are exhausted into the combustionor heating chamber C through the exhaust-valve f. The said products ofcombustion passing through the chamberGand fines g, together with theheat communicated to the water in the water-space a,serve to gencratesteam in the boiler B, which is utilized in driving the steam-engine F,which Is of well-known construction and Will therefore need no specialdescription.

The gas-engine may be of the class which generates the gas as it isused, or it may take gas f rom the streetnnain or from a gas-producer.The parts of the engine which do not admit of being placed under waterare arranged outside the boiler. The boiler is provided with the usualhand-holes and manholes.

By means of my improvement the heat due to the combustion of the gasesin the gas-engine cylinder, which has heretofore been Wasted, isutilized in generating steam for motive power or other uses.

In carrying out, my invention I do not limit or confine myself to anyparticular form of steam-engine, boiler, or gas-engine, nor to anyparticular arrangement of the engine or boiler, as both boiler andengine may be vertical or horizontal, as taste or the requirements ofuse may dictate.

Having thus described my invention, I claim as new and desire to secureby Letters Patenty l. The combination, with a steam-boiler, of agas-engine in the water-space thereof and exhausting into theheating-compartmentor combustion-chamber of the boiler, substantially asset. forth.

2. The combination, with the boiler having a combustion-chamber and awater-chamber at one end communicating with the Waterspace of saidboiler, of a gas-engine the cylinder of which is Within saidWater-chamber and an exhaust-valve connecting said cylinder with thecombustion-chamber, substantially as set forth.

HIPPOLYTE JOSEPH SEIGNEURET.
